李飞飞发布世界模型新成果：一个提示，生成无限3D世界

Core Viewpoint - The article discusses the latest advancements in 3D world generation by Li Fei-Fei's startup, World Labs, highlighting the ability to create expansive, customizable, and consistent 3D environments that can be navigated and explored indefinitely [1][3][27]. Group 1: Model Capabilities - The new model can generate persistent, navigable, and customizable 3D worlds, allowing for seamless integration of multiple independently generated scenes into larger virtual environments [3][25]. - Users can export generated worlds as Gaussian point clouds for use in downstream projects, facilitated by the open-source Spark rendering library, which integrates well with Three.js for web-based 3D experiences [8][12]. - The model supports free viewpoint roaming in a coherent 3D world, enabling users to explore hidden spaces beyond their initial perspective [13][14]. Group 2: Visual Style and Diversity - The model excels in generating diverse visual styles, from cartoonish to realistic, allowing creators to iterate freely on the visual aesthetics of their 3D environments [15][17]. - Users can explore and adjust various styles to find the most suitable virtual world for their needs, enhancing the creative process [16][18]. Group 3: Scale and Exploration - The model allows for the creation of larger virtual worlds by enabling users to combine generated scenes, akin to assembling a puzzle, thus expanding the potential applications of these environments [19][24]. - The generated worlds are designed to be permanently accessible, allowing users to create links and save their work without time constraints, which is a significant advantage over competitors like Google's Genie [28][29].
